Specification of Letters Patent.

Patented Aug. 12,1913.

Original application filed November 3, 1911, Serial No. 658,410. Dividedand this application filed March 26, 1912. Serial No. 686,296.

To all whom it may concern Be it known that I, PETER FILLIEZ, a citizenof the United States, residing at Canton, in the county of Stark andState of Ohio, have invented new and useful Improvements in Grips, ofwhich the following is a specification.

This invention relates to devices for gripping apparatus, andparticularly to wire grippers suitable for use with wire stretchers, anddesigned particularly for use with the device illustrated in mycopending application filed November 3, 1911, Serial No. 658,410, ofwhich this case is a division, although its use is not limited to suchmachines.

It has for its object to provide a grip of simple construction wherebythe cost of manufacture will be minimized, and also has as importantobjects the provision of a simple adjustment for accommodating strandsof various diameters; an actuating spring serving as a retainer forstrands and a positive retaining means adapted to be secured commonlywith the adjustable grip element.

Other objects and advantages will be apparent from the followingdescription, and from the drawings, in which.

Figure l is a plan view of the device, Fig. 2 is a cross sectionthereof.

There is illustrated a base element 21, which may comprise a portion ofany stationary or movable element to hold or move the device against thetension of a strand or other article engaged therewith. It is providedwitha jaw 26 extending laterally therefrom and serrated as at 27 on itsupper side forming transverse parallel ribs and grooves. This jaw has amedial slot 28 transverse to the serrations 27 and opening on the upperand lower faces of the aw and on its outer edge. Spaced from the jaw onthe upper side of the base 21 there is a pivot pin 29 pivoted upon whichthere is a cam dog 30 having an eccentric serrated periphery arranged tobear under rotation against or toward the roughened adjacent face 31 ofan adjustable block 32 serrated on its under side to fit snugly upon theserrations of the jaw 26. This block has also a bolt 33 therethroughdisposed slidably in the slot 28 and engaged with a wing nut 34, wherebythe block is securely held in position when adjusted on the jaw inproper relation to the dog to coengage therewith upon an interposed wireof any thickness. The dog is provided with an arm 35, extendinglaterally from the shank and having a headed pin 36 on its upper sideadjacent its extremity borne upon by the arm 37 of a wire spring havinga helix 38 set'upon a suitable pin carried by the block 32, the oppositeend of the wire being extended to form an arm 39 engaged against a luga0 on the block whereby the arm 37 is caused to exert proper force uponthe dog to cause it to engage properly upon the wire in the device. Itwill be seen that the end of the arm 37 projects somewhat beyond the pin36 whereby it may be disengaged therefrom and thus is adapted to serveas a retainer for wire engaged in the grips, preventing escape of thewire therefrom, its release being eifected by lifting the arm manuallyout. from under the head of the pin, when it will move from over thewire, allowing its ready displacement from between the dog and block.The wire spring may of course be secured suitably against casualdisengagement from the block under pressure of a wire being stretched.

For the secure retention of very heavy wire, or where the arm 37 islikely to be too weak or light, I provide the retaining plate 11longitudinally slotted and held adjustably upon the block by the bolt33. The slot in the plate allows it to be projected across the spacebetween the block and dog or withdrawn, as desired. This space may becalled the throat.

In use, the spring and plate are moved from over the throat, and thewire or other article to be held may be engaged between the dogs andblocks, after which the block 32 is adjusted in proper spaced relationto the dog and if desired, the plate 41 projected over the throat whenthe plate and block are clamped in place by the wing nut and the springis returned to engagement with the dog.

The adjustable feature of the grips is especially advantageous inpermitting the stretching of heavy trolley wires or the lightesttelephone wires with the same implement. It is adapted to allow freemovement of the object to be gripped, in one direction, whereby it isespecially adapted to use upon a wire stretcher including two oppositelyreciprocating members, each of which is provided with one of my grips,whereby both may be engaged with one wire to draw thereupon at eachreciprocation.

What is claimed is:

In a device of the class described, a body member carrying a frictionblock, a cam dog pivoted on the body to bear against the block, a springelement secured upon the block, and having an arm projected across thespace between the block and dog for re- Gopies of this patent may beobtained for five cents each, by addressing the Commissioner of Patents,I

tention of a wire and engaged detachably with the dog for operation ofthe dog, whereby the arm may be displaced for re lease or engagement ofa wire.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
